The 63 published issues of the bi-monthly CHRONICLE OF CURRENT EVENTS (April 1968 to June 1982) can all be accessed in English translation. The Russian original ХРОНИКА ТЕКУЩИХ СОБЫТИЙ has been available online since 2008.
For example — A contemporary account of the events leading up to Alexander Solzhenitsyn‘s expulsion on 13 February from the USSR, see A Chronicle of Current Events (Moscow) CCE 32.1, July 1974.
Most of the Munich-based fortnightly ВЕСТИ ИЗ СССР (November 1978 to December 1991), translated into English as USSR News Brief, is accessible online but only in the Russian original.
For example — The July 1983 trial of Mikhail Rivkin, Vesti iz SSSR (1983, 23-1).
